>> on opening day in the brand- new helen diller playground at north park, children can be seen swinging, gliding, swinging, exploring, digging, hanging, jumping, and even making drumming sounds. this major renovation was possible with the generous donation of more than $1.5 million from the mercer fund in honor of san francisco bay area philanthropist helen diller. together with the clean and safe neighborhood parks fund and the city's general fund. >> 4. 3. 2. 1. [applause] >> the playground is broken into three general areas. one for the preschool set, another for older children, and a sand area designed for kids of all ages. unlike the old playground, the new one is accessible to people with disabilities.
